Aiming at symmetrical crank slider mechanism of high-speed press, a dynamic simulation analysis method combining joint constraint method with MATLAB/Simulink was proposed. First, a velocity equation and an acceleration equation were established based on the closed loop vector equation of displacement. Then, the dynamic equations of mechanism were established by D′Alembert principle, and the kinematic equations and dynamic equations were combined by acceleration. Furthermore, the dynamic simulation model of mechanism was established by MATLAB/Simulink on this basis, and the dynamic equations were embedded in the simulation model as Function module. Thus, the simulation analysis of stamping process for high-speed press was carried out under the stamping force, and the load
and direction variations of each press crankshaft journal in a movement cycle was obtained quickly and accurately. Thus, the good dynamic balance effect of balancer for high-speed press was verified. The results provide important reference for designing and optimizing the high-speed press crankshaft, support structure and dynamic balanced structure.
